P1S AMS Flipper - Top Spool Mount

This model is designed to work for the P1S and the default flipper angle of 75°. It may work work for other printers and configurations, but it definitely does not work for an H2 because the flipper stoppers will not work!

The whole spool mount is made up of 3 elements. 

The Flipper stoppers

The 2 flipper stoppers (left and right). They are designed to prevent the flipper from coming down again, by blocking the joint. They fit in the frame of the AMS to always be available.
I HIGHLY RECOMENDED TO ATTACH SOME KIND OF ANTI-SLIP TAPE TO THEIR BOTTOM!

If the printer wiggles a lot during print, the flipper stoppers can wander if the AMS starts wobbling. It didn't happen to me during printing, but I tested shaking the printer a bit and the stoppers started moving
I used something like this, but anything rubbery would be sufficient. In the print profile, the stoppers have negative cubes you can move into the part to accomodate for the thickness of the tape you use. 

The Spool holder

This goes around the knob of the AMS lid. It goes on and off easily, so be aware to not push it off the knob when mounting the spool. But once the spool is on, it easily holds the 1kg and any additional forces of the extruder.
BE SURE YOUR FILAMENT ISN'T TANGLED!

For obvious reasons, I didn't test this, but I would assume bad things would happen if the extruder would keep pulling on a filament that's stuck on the spool (as with any top spool holder I guess)

The spool holder is designed as a mount for...

TheONE roller

You'll have to print and assemble this separately from this project. If you happen to don't have ball bearings at hand, I'm pretty sure you could just add a cylinder with a stopping cube at the end to the spool holder model in the slicer. If requested, I'll add another print profile that doesn't need the roller

Usage

Lock your AMS lid with the 2 latches, flip it up, remove the top glass (!important, the flipper stoppers will not go in if the glass is still there! ), mount the flipper stoppers, mount the spool holder + roller and you're ready to go

Materials

I used PLA for the stoppers and PETG for the holder, but PLA should work for both. Basically, use any rigid material you have. It seems like there could be a lot of force involved, but if nothing goes wrong (filament tangles!) the forces applied to the parts are minimal and PLA is more than up to the job (given enough walls)
